Incredibly well done! Really nice visuals and that atmosphere as a whole was really good! Gunplay was also really good and those sneaky enemies were very unexpected but a fun challenge. Very solid voice acting as well, especially Rachel's!
Only issue I have is that boss, was a bit awkward to fight against because I had no clue if I was actually doing anything against it. Either way though, not enough to ruin it for me. Very good game as a whole!
